World's largest Multi-Stage Flash (MSF) evaporator, the first of the eight evaporators for the Ras Al Khair Ph.1 seawater desalination plant.

Dec. 13, 2011 -- Doosan Heavy Industries & Construction has successfully completed its fabrication of the world's largest Multi-Stage Flash (MSF) evaporator, the first of the eight evaporators for the Ras Al Khair Ph.1 seawater desalination plant. The unit was shipped from the company's Changwon Plant.

Doosan won the order for the plant project for US$ 1.76 billion from Saline Water Conversion Corporation (SWCC) in the Kingdom of Saudi Arabia in September of last year.

The evaporator unit is capable of producing 91,000 tons of potable water per day, a volume enough for consumption by 300,000 people, making it the largest unit capacity in the world. The evaporator is also the world's largest in size, as it measures 123 meters long, 33.7 meters wide, and weighs 4,150 tons. Transporting the evaporator inland alone requires 30 tractor-trailers with a combined total of 627 wheels.

The previous record for the world's largest evaporator was the unit for the Shuweihat Ph.2 seawater desalination plant, which will be capable of producing 76,000 tons per day upon Doosan's completion of the project. By successfully shipping the evaporator for Ras Al Khair Ph.1, the company has set a new record in fabricating the world's largest evaporator.

Doosan Heavy Industries & Construction will transport the evaporator to the project site in the Kingdom of Saudi Arabia via a sea route for 25 days and will install the unit at the site in late December. The company plans to complete the entire project by March in 2014.
